154 LICHENACEI. [cLaDonza. 
Differs merely in the snow-white colour of the podetia, which become 
hrownish at the apices. The only British specimens seen are sterile. 
Hab. On mossy rocks in maritime and upland tracts.—Distv. Very 
local and scarce in N. England and the S.W. Highlands of Scotland —

Except in the foliaceous podetia this form is also entirely similar to 
the type. It appears to be very rarely fertile, the apothecia when present 
being usually simple and dark-brown. 
Hab. On the ground in upland situations—Distr. Somewhat local, 
though plentiful where it occurs, in England; not yet seen from Scotland 
or Ireland.—B. M.: Shiere, Surrey; Lydd, Kent; Basingstoke, Hants; 
near Cheltenham, Gloucestershire; Malvern, Worcestershire ; Pentregaer, 
Oswestry, Shropshire; near Redcar, Yorkshire; near Hartlepool, Dur- 
ham; Windermere, Westmoreland. 
Subsp. C. muricata Cromb. Grevillea, xi. p. 113.—Podetia some- 
what turgid, rugose, sparingly branched, glabrous or squamulose, 
simple and obtuse or shortly furcate at the apices. Apothecia small, 
dark-brown.—Cladonia furcata var. muricata Nyl. Syn. i. p. 207.

This is amore robust and less-branched plant, having the podetia either 
erect or prostrate, with the cortex rugoso-unequal, usually more or less 
squamulose (form depidota Del.), and occasionally variously difform. It 
somewhat resembles states of subsp. C. racemosa, but it has with K the 
reaction of C. pungens, of which it forms a well-marked subspecies. The 
apothecia are extremely rare in our British specimens. 
Hab. On the ground in upland situations.—Distr. Local, though some- 
what plentiful where it occurs, in §., Central, and W. England.—B. M.: 
Shiere, Surrey ; Basingstoke, Hants; near Amberley, Sussex; Thetford 
Road, Gloucestershire; Bathampton Downs, Somersetshire ; Charnwood 
Forest, Leicestershire. 
23. C. crispata Nyl. Not. Sallsk. pro F. et Fl. Fenn. Forh. n. s. 
v. (1866) p. 110.—Thallus foliaceous at the base; leaflets small, 
incised and crenate, greyish- or greenish-white, sometimes evanes- 
cent; podetia somewhat turgid, glabrous, sometimes 3-4-, usually 
repealedly, branched, concolorous or pale-greyish or subspadiccous,
